[spin-api] upgrade 1.1.2 to 1.2.0 issue SPINModuleRegistry.get().init() fails.

[Jerven Bolleman]

Hi SPIN API/Topbraid developers,

I just attempted to upgrade to the latest spin-api version 1.2.0 from
spin-api 1.1.2.

Code compiles fine but all my test cases fail the moment I attempt to
init the SPINModuleRegistry.get().init();
What should I look at to make it work again.

Regards,
Jerven

e.g. with this kind of stack trace.

Hi Jerven,

I believe you may have the wrong Jena/ARQ versions. The function spl:instanceOf has the following body

ASK WHERE {

    {

        FILTER (isIRI(?arg1) || isBlank(?arg1)) .

        ?class (rdfs:subClassOf)* ?arg2 .

        ?arg1 a ?class .

    }

    UNION

    {

        FILTER isLiteral(?arg1) .

        BIND (datatype(?arg1) AS ?datatype) .

        FILTER (?datatype = ?arg2) .

    } .

}

Upgrading to Jena 2.6.4 and ARQ 2.8.7 will make sure that you have support for the new SPARQL 1.1 features such as BIND (formerly known as LET).

For future reports, please include the full stack trace - the one you sent seems to have been cut off too early so that they real exception wasn't visible. It might explain a SPARQL syntax error - Thanks.

Cheers,

Holger
